SOLOMON H. GOLDBERG, OF CHICAGO, ILLINOIS.

APPARATUS FOR THE MANUFACTURE OF ROOFING MATERIAL.

. Specification of Letters Patent.

Patented Dec. 18, 1917.

Original application filed December 19, 1912, Serial No. 737,652. Divided and this application filed May 25, 1914, Serial No. 840,855. Renewed November 26, 1915. Serial No. 63,677.

Be it known that I, Sonomon H. Gonn- BERG, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for the Manufacture of Roofing Material, of which the following is a specification.

My invention relates to improved apparatus for producing roofing material and more particularl to a roofing material having designs applied to one surface thereof, and this application is a division of my pending application, Serial No. 737,652, filed December 19th, 1912. The apparatus of the present invention is particularly adapted to manufacture a. roofing comprising a strip of backing or foundation material such as paper, felt or the like, treated or saturated with asphaltum or other binder material,

and to one of whose surfaces a granular or comminuted facing of material such as sand, gravel, crushed material or the like, is applied and more specifically applied in designs, as for example, in imitation of shingles, tiles, or the like.

In the roofing and process of making the same which form the basis of the original application above referred to, non-adhesive pattern lines or areas of comminuted material are applied to the saturated and adhesive felt or other backingbefore application thereto of the surfacing material, so that the latter will adhere only to the surface exposed between the pattern lines. I preferably employ some non-adhesive substance, such as powdered or flaked mica, graphite, puml e stone or the like, to form the pattern lines. or areas, this non-adhesive material being applied to the desired portion of the adhesive substance of the roofing backing in designs.

The salient objects of the present invention are to provide an improved apparatus for constructing roofing particularly of the type above referred to; to provide a mechanism in which the non-adhesive substance is preferably applied by means of a printing roll having the pattern raised or embossed on it periphery; to provide a printing roll on which the surfaces of embossed lines or areas are adapted to carry the non-adhesive substance to the adhesive surface of the backing, such as forming the surfaces of the embossed lines or areas somewhat rough- Fig. 2 is an enlarged perspective view of the printing and abutment rolls between wh1c h the backing material passes after an application thereto of the adhesive surface.

F 1g. 3 is a lan view of a section of the I finished product, and

Fig. 4 is a sectlonal view of such product. Referring to Fig. 1, 10 and 11 represent upper and lower rolls, the upper roll being driven in any suitable manner, as by-a' belt 12 drlven from the shaft 13. The body orbacking of the roofing material 14 is'fpro pelled through these rollers and has a coating of adhesive material applied to its upper surface thereby. This coating material is shown as contained in a tank 15 in which it is heated by steam piping 16, a spout 17 dellvering the material to the backing in advance of the upper roll so that as the rolls revolve-this coating material is spreaduni formly over the backing material so that an even coating results. Adjacent the outlet end of the rolls-10 and 11 and in front of the backing emerging from such rolls is the printing roll 18, this roll being journaled in suitable supporting frameworkl9, and the roll being driven as by belt 20 passing around a-suitable pulley on drive shaft 13. Below this printing roll and below the backing is the abutment roll 21 also journaled in the framework 19. The printing roll has on and about its periphery the embossed or raised lines 22 representative of the outline of a pattern, theraised areas forming inthis case outlines of shingles or tiles. Adjacent the printing roll is a trough 23 for containing the non-adhesive material 24 which may be powdered or flaked mica, graphite, pumice stone or any other nonadhesive material. Mounted to revolve in this trough is a roll 25 which dips into the material of the trough and also engages against the outer surfaces of the raised portions of the printing roll in order that the material will better cling to the embossed surfaces, these surfaces may be roughened or otherwise treated and the roll 25 may have a coat 26 of felt or bristles for better carrying the material against the embossing surfaces. When the backing 14 emerges from the rolls 10 and 11 the asphaltic sticky coating which was applied thereto by the rolls will be engaged by the embossed surfaces of the printing roll and the non-adhesive material on these surfaces will be printed or impressed on the sticky surface to form the pattern outlines.

After the pattern outlines have been applied to the adhesive surfaces as described, the backing is ready for receiving the Wearing surfacing material, the asphaltic coating being still warm and sticky. Mounted over the backing where it emerges from the print ing roll is a hopper 27 for containing surfacing sand, gravel, crushed material or the like, and this material falls on the backing to progressively cover the entire top surface thereof, but such material will adhere only to the areas surrounded by the nonadhesive pattern or design lines. After receiving the wearing surfacing coating, the backing travels along a distance .until the adhesive coating has cooled and hardened sufiiciently, the backing then being given a reverse bend about the upper and lower rollers 29 and 30 in order that the loose surfacing material may drop therefrom into .the receptacle 31 from which it is convcyed away as by means of a screw 32. The backing then passes about lower and upper rolls 33 and 34 and then between pressure rolls 35 and 36, such pressure rolls forcing the wearing surfacing material more intimately into engagement with the sticky areas. After this latter treatment, the finished product may be rolled up into marketable rolls. Fig. 2 shows more in detail the operation and effect of the printing roll mechanism, and Figs. 3 and 4: show sections of the finished product.

It may be desirable to face the lower side of the roofing backing for strengthening purposes, as for example by the application thereto of burlap. Such application'may be simultaneously performed with the other steps described above. The strengthening material 37 may be fed from a supplying roll 38 to the underside of the backing to pass therewith between the rolls 10 and 11. Below; the roll 11 a trough 39 contains adhesive material, such as asphaltum,.which .is heated as by means of steam pipes 40. As the rolls 10 and-1 1 rotate, the material from the pan 39 is carried by the rolls 11 against the under side of the material 37 and is the printing roll, the outer face of the material 37 is preferably treated with some non-adhesive substance in order that it will not stick to the abutment roll. A rotary brush 41 is therefore arranged between the rolls 10 and 11 and the abutment roll 21 for brushing non-adhesive substance against the material 37. This substance may be the same substance that is used for forming the pattern lines, and is contained in a suitable trough 42 into which the brush dips.

I thus provide very simple and eflicient mechanism which can be readily applied to roofing material machines to apply pattern or design outlines or areas to the coated surface of the roofing backing before application of the wearing surfacing material thereto. The printing and abutment rolls may be so adjusted that the non-adhesive material carried on the surfaces of the projections will just touch the adhesive coating to stick to this coating; or the adjustment of these rolls can be such that more or less pressure will be applied to the backing so that the non-adhesive substance will be impressed into the adhesive coating.

While I have shown a practical embodiment of my invention, it is obvious that various changes can be made from the mechanism shown and described without departing from the scope of my invention.
